Dense-graded base course consists of crushed stone aggregates with a range of particle sizes, generally 1-1/2 inches or smaller. These materials compact tightly to form a stable stone layer with minimal gaps, providing strong support for various construction and infrastructure applications.

Common Applications for Base Course Crushed Stone
• Foundation layer for asphalt pavements
• Base support for concrete slabs and pavements
• Unsealed roads and road shoulders
• Backfilling around pipes and underground utilities
• Cement-stabilised base construction
